Location, location, location: How to get the steroid where you need it, in chronic rhinosinusitis

What almost all current guidelines on chronic rhinosinusitis have in common is the importance of intranasal steroid (INCS) use. However, it is increasingly understood that the efficacy of INCS depends on their efficient delivery to the point of need, i.e....

The search for the holy grail of rhinosinusitis: another step towards phenotyping in CRS wNP?

For many years, scientists and clinicians have been trying to understand the infinite variability within the term ‘rhinosinusitis’ using radiology, basic science, epidemiology and then using their insights to solve the riddle of management: how to explain why some patients...

The hippo and the nose

Chronic rhinosinusitis with nasal polyps (CRSwNP) leads to histological changes including thickening of the basilar membrane and epithelial proliferation. Molecular mechanisms underlying these changes are still not fully clear. A signalling pathway called the hippo with Yes‐associated protein (YAP) as...

CRSwNP, another monoclonal antibody

Interleukins 4, 5 and 13 were shown to be important factors in type 2 inflammation, which characterises chronic rhinosinusitis with nasal polyposis (CRSwNP). In CRSwNP non-responders and those who recur short after-surgery monoclonal antibodies might be an answer. Examples include...

Chronic rhinosinusitis, are we treating the same disease?

Chronic rhinosinusitis (CRS) is a heterogenic disease. The effects of heterogeneity on treatment outcome are not very clear. Authors used clinical features such as endoscopic findings scores and full blood count findings in addition to analysis of 35 molecular markers....

Method of delivery: all topical nasal corticosteroids are not made equal

There is an increasing body of evidence that the role of surgery for chronic rhinosinusitis is to facilitate the delivery of topical medical treatment – most notably, topical corticosteroids. Two recent studies, one using flow dynamics and another one examining...

IL-25 and nasal polyps, another target

Immune response in chronic rhinosinusitis with nasal polyps (CRSwNP) is mainly via type 2 T-helper (Th2) cells while Th1 cells characterise chronic rhinosinusitis without nasal polyps (CRSsNP) immune response. CRSwNP is heterogeneous on a cytological level causing a varied response...

Stem cells in nasal polyposis

Chronic rhinosinusitis with nasal polyps (CRSwNP) is common and is multifactorial with increased T-helper 2 response and active role of interleukin 5. It can be associated with asthma and control of CRSwNP improves lower airway disease. Due to constant cellular...
